The software sources for old out of date ubuntu and ultimate edition such as the 2.8 and 2.6 has a new repository held by ubuntu and vary soon Systak Solutions. We are taking in the old ultimate edition 2.8 for a rebuild and update in systems. We will be hosting a repository at archive.artistxlinux.com/repository

I don't quite understand. Without so much as glancing at correlating Ubuntu versions to 2.6,2.8..something like..10.##,11.##?, I have heard of no such support structure nor would I quite understand how this is accomplished through corresponding zip file. While I understand Ubuntu itself is creating a dynamic to deal with individual structures without consulting multiversion dependencies, "snaps", this has little to do with support structure in terms of older/outdated systems. I will look into this further, later.

Edit: I am not exactly unfamiliar with repo structure, If you could post ".list", would be cool, too. I will if I remember to get on Linux machine, later.

the zip file must be extracted. it contains two files sources.list and sources.bak

Ubuntu repositories in say Ultimate edition 2.8 refer to us.archive.ubuntu.com. since these are not supported versions the sources must be updated to there current location. old-releases.ubuntu.com. My repository is not up yet so the new location of the ubuntu repositories is how you get them to work.
